8 Claims. (Cl. 20-71) The inventionrelates to window guards andspecifically to guards for casement windows.

The unguarded, open casement windows of large metropolitan apartmenthouses are principally casement windows which have proven to be prolificcauses of accidents, many fatal, which occur when infants, sometimesadults, fall from the open windows.

Various expedients have been employed to lessen or prevent theseaccidents but few have proven efficacious, some of the inherentdisadvantages being difl'iculty of installation, high cost or otherdrawbacks.

One of the objects of my invention is the provision of a window guardwhich will prevent accidents and can be quickly installed on a windowcasement with the simplest of tools, and is virtually tamper-proof.

Another object comprehends a window guard which requires no mechanicalaptitude to install.

Still another object contemplates a window guard, the components ofwhich can be mass produced and sold at low cost, within the budgetaryrequirements of virtually every apartment dweller.

I provide a window guard which for the minimum investment will protectevery member of the family.

Briefly described, the invention comprises a pair of clamps, attachableat opposite sides or top and bottom of a casement window and adjustablewhen necessary, for use in conjunction with a bar held by the clamps tocross the window opening and prevent persons from falling therethrough.The clamps are provided with threaded bolts for tightening the clamps tothe window casement, and a centrally positioned threaded bolt member fortightly securing the bar in the clamp, said bar insertable in each clampin an opening or aperture therein. And I contemplate that one or morethan one bar may be employed, held by one or more pairs of clamps, or aplurality of horizontal bars sustained in spaced relationship byvertical bars, and vice-versa.

in the drawings:

Figure 1 is a top plan view showing the invention in use;

Fig. 2 depicts an exploded perspective view;

Fig. 3 is a cross-section taken along the line 33 of Fig. 1;

Fig. 4 is a cross-section taken along the line 4-4 of Fig. 1;

Fig. 5 is a front plan view of a modified form schematically showing around or a hexagonal bar being used;

Fig. 6 is a cross section of a modified form of the invention takenalong the line 6-6 of Fig. 5;

Fig. 7 is a plan view of another modification.

Referring to the drawings, the clamps 5, of which a pair or pairs arerequired, dimensioned and formed alike, may be produced from a blank oflightweight material, such as aluminum, magnesium, alloys thereof, orfrom any other metal or material having the desired inherent strengthand rigidity. And in reference to said clamps, like numerals areintended and do refer to like parts.

Clamp 5 is provided with a pair of spaced flanges 6-7 extending fromback 8, said flanges being parallel to one another, are disposed atright angles to the back, and at their inner sides they merge into saidback.

Midway of the back and closer to flange 7 than to flange 6, I provide anopening 9 which in the preferred embodiment of the invention defines acircular aperture, although it may be as suggested in Fig. 5 shaped tolit the peripheries of any bar stock other than round. Additionally, Icontemplate using flat steel bent to any desired shape to fit theaperture, tube stock, both square, hex and round may be used, plasticstock or wood or any material having the desired strength.

Threaded through the opposite ends of flange 7, are bolts 10, which whenthreaded home, impinge against flange 6 and hold between their lowerterminals and one face of the flange, the easement C of a window.

Centrally located with respect to flange 7, toward back 8, and threadedvertically through said flange is bolt 11, which, as illustrated in Fig.3, secures bar 12 in clamp 5 when said bar is thrust through theaperture 9 in back 8 of said clamp.

In Fig. 5 is illustrated a modification wherein the.aperture is shapedwith a semicircular-like top 13, having shoulders 14, and the opening 15is defined-extends between flanges 16 which also extend at right anglesfrom the back 17 and parallel to each other. In this embodiment threadedbolts 18 are threaded through upper flange 19 and bolt 20, threadedthrough said flange, causes bar 12 to be held against casement C whenthe bolt is tightened. A capital advantage of this modification is thatthis aperture is capable of taking bars of different peripheralconfigurationtwo different ones being illustrated positioned.

As is readily understood, the bolts illustrated in the clamps are fittedwith Allen type heads, and the well known Allen wrench can be employedto quickly tighten the clamps 5 in the desired position on the casementwindow, and the same wrench used to tighten bolt 11 against bar 12. Oneadvantage of using an Allen head is to preclude tampering with themounted guard, and any unwanted loosening of the clamps or bar bychildren or others. But other types of heads may be used. One advantageof threading bolt 11 through flange 7 on the side nearer to back 8 isthat there is less strain on the diverging angle between flange 7 andback 8 when the bolt 11 is tightened against bar 12. Bar 12 may bepositioned horizontally or vertically, as shown in Fig. 1, and, ofcourse, the location of clamps 5 may be higher or lower on the casementthan the location depicted in said Fig. 1. Positioning the window guardis a matter of choice, the end result being maximum safety for theentire household. And, as before stated, instead of one bar, there maybe a plurality of bars employed, secured by additional pairs of clamps5. Further, another advantage of providing the apertures in the saidclamps is that the bars are removable for window washing and otherpurposes without having to remove the clamps.

Finally, as shown in Fig. 7, I contemplate using a guard comprising, forexample, horizontal bars 21 and 22 held fixedly spaced apart by verticalbars 23, 24, 25 welded or otherwise secured to bars 21 and 22. Thisguard is positioned at any desired place on the window, by placing theclamps where required.

The components, as mentioned before, may be mass produced and for amodest sum a window guard may be bought for every window in anapartment. While a single casement window is shown, the guard isadaptable to double casement windows, and, for that matter, any typewindow having a casement to which clamps 5 are afiixable.

I reserve the right to make such changes or modification more thanonebar.

3 tions as may come within the scope of the appending claims.

For example, the clamps 5 may be made of greater overall length, andmore than one aperture may be provided so that a singlepairof clamps canbe used to posi- And other modifications are, of course, within thescope of the invention.
